Description

Die Erfindung betrifft ein Hörgerät mit Audioschuh-Schnittstelle, einen zugehörigen Audioschuh, sowie ein Hörgerätesystem umfassend ein Hörgerät und einen Audioschuh.The invention relates to a hearing aid with audio shoe interface, an associated audio shoe, and a hearing aid system comprising a hearing aid and an audio shoe.

Hörgeräte sind tragbare Hörvorrichtungen, die zur Versorgung von Schwerhörenden dienen. Um den zahlreichen individuellen Bedürfnissen entgegenzukommen, werden unterschiedliche Bauformen von Hörgeräten wie Hinter-dem-Ohr-Hörgeräte (HdO, BtE: Behind-the-Ear), Hörgerät mit externem Hörer (RIC: Receiverin-Canal) und In-dem-Ohr-Hörgeräte (IdO), Concha-Hörgeräte oder Kanal-Hörgeräte (ITE: In-the-Ear, CIC: Completely-in-Canal) bereitgestellt. Die beispielhaft aufgeführten Hörgeräte werden am Außenohr oder im Gehörgang getragen.Hearing aids are portable hearing aids that are used to care for the hearing impaired. To meet the numerous individual needs, different types of hearing aids such as behind-the-ear hearing aids (BTE, BtE: Behind-the-Ear), hearing aid with external handset (RIC: Receiverin-Canal) and in-the-ear Hearing aids (IdO), Concha hearing aids or canal hearing aids (ITE: In-the-Ear, CIC: Completely-in-Canal). The hearing aids listed by way of example are worn on the outer ear or in the ear canal.

Ein Hörgerät besitzt als wesentliche Komponenten einen Eingangswandler, Signalverarbeitungselemente, einen Verstärker und einen Ausgangswandler. Der Eingangswandler ist in der Regel ein Schallempfänger, z. B. ein Mikrofon, und/oder ein elektromagnetischer Empfänger, z. B. eine Induktionsspule. Der Ausgangswandler ist meist als elektroakustischer Wandler, z. B. Miniaturlautsprecher, oder als elektromechanischer Wandler, z. B. Knochenleitungshörer, realisiert. Der Verstärker ist üblicherweise in eine Signalverarbeitungseinheit integriert. Die Stromversorgung des Hörgeräts erfolgt durch eine ins Hörgerätegehäuse integrierte Batterie. Die wesentlichen Komponenten eines Hörgerät sind in der Regel auf einer gedruckten Leiterplatine als Schaltungsträger angeordnet bzw. damit verbunden.A hearing aid has as essential components an input transducer, signal processing elements, an amplifier and an output transducer. The input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil. The output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized. The amplifier is usually integrated in a signal processing unit. The hearing aid is powered by a battery integrated into the hearing aid housing. The essential components of a hearing aid are usually arranged on a printed circuit board as circuit carrier or connected thereto.

Es gibt Hörgeräte, deren Funktionsumfang durch Anstecken eines sogenannten Audioschuhs erweitert werden kann. Als Audioschuh wird ein ansteckbares, separates Funktionsmodul bezeichnet, dass beispielsweise Telefonfunktionen, Unterhaltungselektronik wie Radio, Schnittstellen zu Unterhaltungselektronik wie MP3-Player, umfassen kann. Zahlreiche Hörgeräte besitzen die Möglichkeit, über einen speziellen Audioschuh Audiosignale einzukoppeln. Hierzu wird in den Audioschuh ein externes Audiogerät eingesteckt. Der Audioschuh bildet dann die Schnittstelle zwischen dem Hörgerät und dem externen Audiogerät. Nachfolgend sollen mit dem Begriff Audioschuh alle denkbaren separaten Komponenten bezeichnet sein, die durch eine lösbare mechanische und/oder elektrische Verbindung mit einem Hörgerät verbunden werden können.There are hearing aids whose functionality can be extended by attaching a so-called audio shoe. As an audio shoe an attachable, separate functional module is called that, for example, phone functions, consumer electronics such as radio, interfaces with consumer electronics like mp3 player, may include. Numerous hearing aids have the option of coupling in audio signals via a special audio shoe. For this purpose, an external audio device is plugged into the audio shoe. The audio shoe then forms the interface between the hearing aid and the external audio device. In the following, all conceivable separate components are to be designated by the term audio shoe, which can be connected to a hearing device by a detachable mechanical and / or electrical connection.

Hörgeräte, die mit Audioschuh verwendet werden können, weisen mindestens eine Anschlusskontaktstelle zum Anschließen eines Audioschuhs an die Leiterplatine des Hörgeräts oder an dessen elektronische Komponenten auf. Ein zugehöriger Audioschuh weist entsprechende Anschlusskontaktelemente auf. Die Verbindung zwischen Audioschuh und Hörgerät muss zum einen mechanisch fest sein, und zum anderen einen elektronischen Kontakt vermitteln.Hearing aids that can be used with audio shoe have at least one connection pad for connecting an audio shoe to the circuit board of the hearing aid or to its electronic components. An associated audio shoe has corresponding terminal contact elements. The connection between the audio shoe and the hearing aid has to be mechanically strong on the one hand, and on the other must mediate electronic contact.

Üblicherweise besitzt ein Audioschuh mehrere Kontakte, z. B. vier Stück, die mit entsprechenden Kontakten auf der Leiterplatine oder auf Komponenten des Hörgeräts kontaktiert werden müssen. Da sich Leiterplatine und Komponenten üblicherweise im Mittelbereich des Hörgerätegehäuses befindet, wohingegen der Audioschuh an dem dem Hörer gegenüberliegenden Ende (Batteriefachende) eingesteckt oder angeordnet ist, wird häufig ein spezielles Zwischenstück vorgesehen, um die Kontakte von Audioschuh und Hörgerät zu verbinden. In das Zwischenstück sind Metallkontakte eingeformt, die dann an der Außenseite des Hörgeräts liegen. Diese Kontakte korrodieren oftmals, so dass es Kontaktprobleme gibt. Aus diesem Grund werden in der Regel für den Audioschuh spezielle Abdeckklappen benötigt. Ein weiterer Nachteil des separaten Zwischenstücks besteht darin, dass die Montagezeit für ein Hörgerät durch dieses separate Teil zunimmt.Typically, an audio shoe has multiple contacts, eg. B. four pieces that need to be contacted with appropriate contacts on the circuit board or components of the hearing aid. Since the printed circuit board and components are usually located in the middle region of the hearing aid housing, whereas the audio shoe is inserted or arranged at the end opposite the handset (battery end), a special intermediate piece is often provided in order to connect the contacts of the audio shoe and the hearing aid. In the intermediate piece metal contacts are formed, which then lie on the outside of the hearing aid. These contacts often corrode, so there are contact problems. For this reason, special cover flaps are usually required for the audio shoe. Another disadvantage of the separate intermediate piece is that the assembly time for a hearing aid increases by this separate part.

Aus der Druckschrift US2009/041277A1 ist ein Hinter-dem-Ohr-Hörgerät bekannt, an dem ein Audioschuh lösbar an einer Stirnseite des Gehäuses koppelbar ansteckbar ist. Eine Kopplungseinrichtung am Hörgerät umfasst eine mechanische Führung, in die der Audioschuh durch eine Schiebebewegung parallel zu der Stirnseite des Hörgeräts einsteckbar ist. Eine Sicherungseinrichtung in Form eines quer zu der Schieberichtung des Audioschuhs beweglichen Schiebers verhindert eine ungewollte Schiebebewegung des Audioschuhs.From the publication US2009 / 041277A1 For example, a behind-the-ear hearing device is known in which an audio shoe can be detachably connected to one end of the housing in a detachable manner. A coupling device on the hearing device comprises a mechanical guide, into which the audio shoe can be inserted by a sliding movement parallel to the front side of the hearing device. A safety device in the form of a slider movable transversely to the sliding direction of the audio shoe prevents unwanted sliding movement of the audio shoe.

Ein nichtindividuelles elektronisches Modul kann in eine dafür vorgesehene Öffnung des Gehäuses eingesetzt werden. Dazu ist ein Schwenk-Rastmechanismus in der Gehäuseöffnung vorgesehen, in den das Modul durch eine Schwenk-Bewegung mechanisch eingerastet wird. Aus der Druckschrift EP 2 012 556 A1 ist ein Hinter-dem-Ohr-Hörgerät mit ansteckbarem Audioschuh bekannt, der in einer Schiebebewegung mit dem Gerät verbunden wird. Die Aufgabe der Erfindung besteht darin, eine Hörgerät-Audioschuh-Schnittstelle zu schaffen, die mechanisch stabil ist, die die elektrischen Kontaktstellen gegen äußere Einflüsse möglichst gut schützt, die optisch möglichst wenig sichtbar ist, die einfach zu handhaben ist, und die unaufwändig herzustellen ist.From the publication EP 1 838 134 A1 is an ITE hearing aid with individually shaped housing known. A non-individual electronic module can be inserted into a designated opening of the housing. For this purpose, a pivot-locking mechanism is provided in the housing opening, in which the module is mechanically engaged by a pivoting movement.

Die Erfindung löst diese Aufgabe durch ein Hörgerät, einen Audioschuh, und ein Hörgerätesystem mit Hörgerät und Audioschuh mit den Merkmalen der unabhängigen Patentansprüche. Vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Patentansprüchen.The invention solves this problem by a hearing aid, a Audio shoe, and a hearing aid system with hearing aid and audio shoe with the features of the independent claims. Advantageous developments emerge from the dependent claims.

Ein Grundgedanke der Erfindung besteht in einem Hörgerät, umfassend ein Gehäuse, wobei in dem Gehäuse eine Öffnung, eine Vertiefung, eine Hinterschneidung und ein Widerlager vorgesehen sind. Die Vertiefung, die Hinterschneidung und das Widerlager stehen mit der Öffnung in Verbindung. Das Widerlager ist auf einer der Hinterschneidung gegenüber liegenden Seite der Öffnung angeordnet. Die Öffnung, die Vertiefung, die Hinterschneidung und das Widerlager sind derart ausgeführt, dass eine Haltenase eines Audioschuhs durch die Öffnung und Vertiefung hindurch mit einer Rotationsbewegung um die im Bereich der Hinterschneidung liegende Seite der Öffnung herum hin in die Hinterschneidung einführbar ist. Das Widerlager ist derart ausgeführt, dass eine in die Hinterschneidung eingeführte Haltenase nur durch eine Rotationsbewegung um die im Bereich der Hinterschneidung liegende Seite der Öffnung herum aus der Hinterschneidung ausführbar ist. Weiter ist eine Verriegelung vorgesehen, die derart ausgeführt ist, dass eine Verriegelungskomponente eines in die Hinterschneidung eingeführten Audioschuhs damit verriegelbar ist gegen eine Rotationsbewegung um die im Bereich der Hinterschneidung liegende Seite der Öffnung herum aus der Hinterschneidung heraus.A basic idea of the invention consists in a hearing device, comprising a housing, wherein in the housing an opening, a recess, an undercut and an abutment are provided. The recess, the undercut and the abutment are in communication with the opening. The abutment is arranged on one of the undercut opposite side of the opening. The opening, the recess, the undercut and the abutment are designed such that a retaining lug of an audio shoe can be introduced through the opening and recess with a rotational movement about the side of the opening lying in the region of the undercut into the undercut. The abutment is designed such that an inserted into the undercut retaining lug is executed only by a rotational movement about the lying in the region of the undercut side of the opening from the undercut. Further, a lock is provided, which is designed such that a locking component of an inserted into the undercut audio shoe is lockable against rotation about the side lying in the region of the undercut side of the opening from the undercut out.

Die Hinterschneidung im Gehäuse gewährleistet eine hohe Stabilität der mechanischen Verbindung zwischen Gehäuse und Audioschuh. Sie ermöglicht den Verzicht auf aus dem Gehäuse herausstehende Komponenten und ist daher optisch und in der Handhabung gefällig. Es werden keine zusätzlichen separaten Bauteile wie Achsen, Achsaufnahmen, o.ä. für die mechanische Verbindung benötigt, so dass sie in der Fertigung hinsichtlich der Fertigungsschritte und Bauteile-Logistik günstig ist.The undercut in the housing ensures a high stability of the mechanical connection between the housing and the audio shoe. It eliminates the need for protruding from the housing components and is therefore pleasing visually and in handling. There are no additional separate components such as axles, axle mounts, or similar. needed for the mechanical connection, so that it is favorable in terms of manufacturing steps and component logistics in manufacturing.

Eine vorteilhafte Weiterbildung besteht darin, dass auf der Innenseite der Gehäuseaußenwand im Bereich der Hinterschneidung elektrische Kontaktflächen angeordnet sind. Die Kontaktflächen sind durch die Öffnung und Hinterschneidung hindurch zugänglich. Durch die Anordnung in der Hinterschneidung sind die Kontaktflächen von außen nicht sichtbar, was optisch gefällig ist. Zudem sind sie dadurch gegen mechanische Abnutzung durch Berührungen aller Art und gegen Umwelteinflüsse wie Feuchtigkeit, Wasser, Staub, Schmutz geschützt.An advantageous development is that on the Inside the housing outer wall in the region of the undercut electrical contact surfaces are arranged. The contact surfaces are accessible through the opening and undercut. Due to the arrangement in the undercut, the contact surfaces are not visible from the outside, which is visually pleasing. In addition, they are thus protected against mechanical wear due to touch of any kind and against environmental influences such as moisture, water, dust, dirt.

Eine weitere vorteilhafte Weiterbildung besteht darin, dass die Verriegelung als Einkerbung mit einer Rastnase ausgeführt ist. Dadurch ergibt sich ein besonders einfach handhabbarer Verriegelungsmechanismus. Es werden keine zusätzlichen Verriegelungs-Bauteile benötigt, was in der Fertigung hinsichtlich der Fertigungsschritte und Bauteile-Logistik günstig ist.A further advantageous development is that the locking is designed as a notch with a locking lug. This results in a particularly easy-to-handle locking mechanism. There are no additional locking components needed, which is favorable in terms of manufacturing steps and component logistics in manufacturing.

Die Kombination von Hinterschneidung und Verriegelung ist wie vorangehend erläutert derart ausgeführt, dass ein Audioschuh mit einer Kombination von Schiebe- und Rotationsbewegung in die Hinterschneidung eingeführt und dann mit fortsetzen der Bewegung mit der Verriegelung verriegelt werden kann. Diese Schiebe-Rotations-Bewegung ist einfach ausführbar. Die Haltenase muss dabei zunächst nur relativ grob in die GehäuseÖffnung eingeführt werden und wird sodann durch die Rotationsbewegung des Audioschuhs selbsttätig in die exakte Endposition geführt. Daher erfordert die Schiebe-Rotations-Bewegung keine besondere Präzision in der Positionierung und Ausführung der Bewegung, was die Handhabung erleichtert.The combination of undercut and lock is as previously discussed so implemented that an audio shoe can be inserted into the undercut with a combination of sliding and rotational motion and then locked to resume movement with the latch. This sliding-rotation movement is easy to execute. The retaining lug must first be introduced relatively coarse into the housing opening and is then automatically guided by the rotational movement of the audio shoe in the exact end position. Therefore, the sliding-rotation movement does not require any particular precision in the positioning and execution of the movement, which facilitates handling.

In einer weiteren vorteilhaften Weiterbildung ist die Vertiefung bogenförmig um die im Bereich der Hinterschneidung liegende Seite der Öffnung herum gestaltet. Die bogenförmige Gestaltung unterstützt die Rotationsbewegung des Audioschuhs beim Einführen der Haltenase in die Hinterschneidung. Dadurch wird die Handhabung zusätzlich erleichtert.In a further advantageous embodiment, the recess is arcuately designed around the lying in the region of the undercut side of the opening around. The arcuate design supports the rotational movement of the audio shoe when inserting the retaining lug in the undercut. This makes handling easier.

Ein weiterer Grundgedanke der Erfindung besteht in einem Audioschuh mit einer Haltenase und einer Verriegelungskomponente. Die Haltenase ist derart ausgeführt, dass sie in eine wie vorangehend erläutert ausgeführte Hinterschneidung in einem Gehäuse eines Hörgeräts mit einer Rotationsbewegung um die im Bereich der Hinterschneidung liegende Seite der Öffnung herum eingeführt werden kann. Die Verriegelungskomponente ist derart ausgeführt, dass sie mit einer wie vorangehend erläutert ausgeführten Verriegelung eines Hörgeräts in gegenseitigen verriegelnden Eingriff gebracht werden kann, z.B. als Riegel oder Stift oder Bolzen.Another basic idea of the invention is an audio shoe with a retaining lug and a locking component. The retaining lug is designed such that it can be inserted into an undercut as explained above in a housing of a hearing aid with a rotational movement about the side of the opening located in the region of the undercut. The locking component is designed such that it can be brought into mutual locking engagement with a locking device of a hearing aid, as explained above, eg as a bolt or pin or bolt.

Die Haltenase kann ohne weiteres so ausgeführt werden, dass eine hohe Stabilität der mechanischen Verbindung zwischen Gehäuse und Audioschuh gewährleistet ist. Sie kann derart an den Audioschuh angeformt sein, dass keine zusätzlichen separaten Bauteile wie Achsen, Achsaufnahmen, o.ä. für die mechanische Verbindung benötigt werden, beispielsweise kann sie einstückig als Spritzgussteil angeformt sein. Dies ist in der Fertigung hinsichtlich der Fertigungsschritte und Bauteile-Logistik günstig.The retaining lug can be easily carried out so that a high stability of the mechanical connection between the housing and audio shoe is ensured. It can be molded onto the audio shoe in such a way that no additional separate components such as axles, axle mountings, or the like are used. For the mechanical connection needed, for example, it may be integrally formed as an injection molded part. This is favorable in manufacturing in terms of manufacturing steps and component logistics.

In einer vorteilhaften Weiterbildung sind auf der Haltenase elektrische Kontaktflächen angeordnet. Die Kontaktflächen der Haltenase sind so angeordnet, dass sie durch das Einführen der Haltenase in eine wie vorangehend erläutert ausgeführte Hinterschneidung eines Gehäuses eines Hörgerätes mit wie vorangehend erläutert in der Hinterschneidung angeordneten elektrischen Kontaktflächen in Kontakt gebracht werden. Durch die Anordnung in der Hinterschneidung - bei eingeführter Haltenase - sind die Kontaktflächen von außen nicht sichtbar, was optisch gefällig ist. Sie sind zudem gegen mechanische Abnutzung durch Berührungen aller Art und gegen Umwelteinflüsse wie Feuchtigkeit, Wasser, Staub, Schmutz geschützt.In an advantageous development, electrical contact surfaces are arranged on the retaining lug. The contact surfaces of the retaining lug are arranged such that they are brought into contact by the insertion of the retaining lug in an undercut as explained above of a housing of a hearing aid with arranged as explained above in the undercut electrical contact surfaces. Due to the arrangement in the undercut - with inserted retaining lug - the contact surfaces are not visible from the outside, which is visually pleasing. They are also protected against mechanical wear due to touch of any kind and against environmental influences such as moisture, water, dust, dirt.

In einer weiteren vorteilhaften Weiterbildung wird die Verriegelungskomponente, wenn der Audioschuh mit der Haltenase in eine wie vorangehend erläutert ausgeführte Hinterschneidung eines Gehäuses eines Hörgeräts eingeführt ist, durch eine elastische Kraft beaufschlagt. Durch die elastische Kraft, beispielsweise erzeugt durch eine Feder oder ein elastisches Formgedächtnisbauteil, wird die Verriegelungskomponente mit der Verriegelung in gegenseitigen Eingriff gebracht. Dadurch wird die Verriegelung selbsttätig geschlossen, was zum einen eine einfache Handhabung bewirkt, zum anderen eine hohe Sicherheit gegen unbeabsichtigtes Lösen der Verriegelung.In a further advantageous development, when the audio shoe with the retaining lug is inserted into an undercut of a housing of a hearing aid, as explained above, the locking component is replaced by a elastic force applied. By the elastic force, for example generated by a spring or an elastic shape memory component, the locking component is brought into mutual engagement with the lock. As a result, the lock is automatically closed, which on the one hand causes easy handling, on the other hand, a high level of security against unintentional release of the lock.

In einer weiteren vorteilhaften Weiterbildung ist die die Oberfläche der Haltenase auf der Seite konvex bogenförmig gestaltet. Und zwar ist diejenige Oberfläche so gestaltet, die beim Einführen in eine Hinterschneidung in einem wie vorangehend ausgeführten Gehäuse eines Hörgeräts mit bogenförmiger Vertiefung zu der Vertiefung hin orientiert ist. Die konvex bogenförmige Oberfläche nimmt in gewisser Weise die (von außerhalb des Gehäuses betrachtet) konkave Bogenform der Vertiefung auf. Dadurch wird die Rotationsbewegung beim Einführen der Haltenase in Richtung der Hinterschneidung geführt. Dies verbessert die Präzision der Positionierung der Haltenase beim Einführen. Zudem erleichtert es die Einführbewegung. Somit wird eine leichtere Handhabung erreicht.In a further advantageous embodiment, the surface of the retaining lug on the side convexly curved. Namely, that surface is designed so that when inserted into an undercut in a previously executed housing of a hearing aid with arcuate recess is oriented towards the recess. The convexly arcuate surface takes up, in some way, the concave arc shape of the recess (as viewed from outside the housing). As a result, the rotational movement during insertion of the retaining lug is guided in the direction of the undercut. This improves the precision of the positioning of the retaining lug during insertion. It also facilitates the insertion movement. Thus, easier handling is achieved.

Ein weiterer Grundgedanke besteht in einem Hörgerätesystem, das ein wie vorangehend erläutert ausgeführtes Hörgerät und einen wie vorangehend erläutert ausgeführten Audioschuh umfasst.Another basic idea is a hearing device system that includes a hearing aid designed as described above and an audio shoe designed as explained above.

Die mechanische Verbindung auf Basis der Hinterschneidung im Gehäuse und der Haltenase des Audioschuhs gewährleistet eine hohe Stabilität. Sie ermöglicht den Verzicht auf aus dem Gehäuse herausstehende Komponenten und ist daher optisch und in der Handhabung gefällig. Es werden keine zusätzlichen separaten Bauteile wie Achsen, Achsaufnahmen, o.ä. für die mechanische Verbindung benötigt, so dass sie in der Fertigung hinsichtlich der Fertigungsschritte und Bauteile-Logistik günstig ist.The mechanical connection based on the undercut in the housing and the retaining lug of the audio shoe ensures high stability. It eliminates the need for protruding from the housing components and is therefore pleasing visually and in handling. There are no additional separate components such as axles, axle mounts, or similar. needed for the mechanical connection, so that it is favorable in terms of manufacturing steps and component logistics in manufacturing.

Sind zusätzlich auch die elektrischen Kontaktflächen innerhalb der Hinterschneidung angeordnet, so sind sie von außen nicht sichtbar, was optisch gefällig ist. Zudem sind sie dadurch gegen mechanische Abnutzung durch Berührungen aller Art und gegen Umwelteinflüsse wie Feuchtigkeit, Wasser, Staub, Schmutz geschützt.Are in addition also the electrical contact surfaces within arranged the undercut, so they are not visible from the outside, which is visually pleasing. In addition, they are thus protected against mechanical wear due to touch of any kind and against environmental influences such as moisture, water, dust, dirt.

Die Kombination von Hinterschneidung und Verriegelung ist wie vorangehend erläutert derart ausgeführt, dass ein Audioschuh mit einer Kombination von Schiebe- und Rotationsbewegung in die Hinterschneidung eingeführt und dann mit fortsetzen der Bewegung mit der Verriegelung verriegelt werden kann. Diese Schiebe-Rotations-Bewegung ist einfach ausführbar. Die Haltenase muss dabei zunächst nur relativ grob in die GehäuseÖffnung eingeführt werden und wird sodann durch die Rotationsbewegung des Audioschuhs selbsttätig in die exakte Endposition geführt. Daher erfordert die Schiebe-Rotations-Bewegung keine besondere Präzision in der Positionierung und Ausführung der Bewegung, was die Handhabung erleichtert.The combination of undercut and lock is as previously discussed so implemented that an audio shoe can be inserted into the undercut with a combination of sliding and rotational motion and then locked to resume movement with the latch. This sliding-rotation movement is easy to execute. The retaining lug must first be introduced relatively coarse into the housing opening and is then automatically guided by the rotational movement of the audio shoe in the exact end position. Therefore, the sliding-rotation movement does not require any particular precision in the positioning and execution of the movement, which facilitates handling.

Sind die Vertiefung bzw. die Haltenase zudem bogenförmig konkav bzw. konvex gestaltet, so wird die Rotationsbewegung des Audioschuhs beim Einführen der Haltenase in die Hinterschneidung unterstützt. Dadurch wird die Rotationsbewegung beim Einführen der Haltenase in Richtung der Hinterschneidung geführt. Dies verbessert die Präzision der Positionierung der Haltenase beim Einführen. Zudem erleichtert es die Einführbewegung. Somit wird eine leichtere Handhabung erreicht.If the depression or retaining lug is also arc-shaped concave or convex, the rotational movement of the audio shoe during insertion of the retaining lug into the undercut is assisted. As a result, the rotational movement during insertion of the retaining lug is guided in the direction of the undercut. This improves the precision of the positioning of the retaining lug during insertion. It also facilitates the insertion movement. Thus, easier handling is achieved.

Wird die Verriegelungskomponente des Audioschuhs zudem durch eine elastische Kraft, beispielsweise erzeugt durch eine Feder oder ein elastisches Formgedächtnisbauteil, mit der Verriegelung in gegenseitigen Eingriff gebracht und die Verriegelung selbsttätig geschlossen, ergibt sich auch hier eine einfache Handhabung. Zudem wird eine hohe Sicherheit gegen unbeabsichtigtes Lösen der Verriegelung gewährleistet.If the locking component of the audio shoe is additionally brought into mutual engagement with the lock by an elastic force, for example generated by a spring or an elastic shape memory component, and the lock is automatically closed, an easy handling also results here. In addition, a high level of security against unintentional release of the lock is ensured.

In Figur 1 ist ein Hörgerät 1 mit Audioschuh 2 schematisch dargestellt. Das Hörgerät 1 weist die Gehäuseform eines HdO-Gerätes auf. Die Batterie ist in einer Batterielade 15 im breiten, abgerundeten Ende des Gehäuses angeordnet. Die Batterielade 15 weist einen Hebel 5 auf, mit dem sie geöffnet werden kann.In FIG. 1 is a hearing aid 1 with audio shoe 2 shown schematically. The hearing aid 1 has the housing shape of a BTE device. The battery is disposed in a battery tray 15 in the wide, rounded end of the housing. The battery door 15 has a lever 5, with which it can be opened.

Der Audioschuh 2 ist auf das Hörgerät 1 aufgesteckt. Er überdeckt die Batterielade 15 samt Hebel 5, welche deshalb strichliert dargestellt sind. Er ist mit einer in das Hörgerät 1 hineinreichenden Haltenase 8 und einer Verriegelungskomponente 4 auf dem Hörgeräte-Gehäuse verriegelt.The audio shoe 2 is attached to the hearing aid 1. He covers the battery door 15 together with lever 5, which are therefore shown in dashed lines. He is locked with a reaching into the hearing aid 1 retaining lug 8 and a locking component 4 on the hearing aid housing.

In Figur 2 ist ein Schnittbild eines Teils eines Hörgerätes 1 und ein Schnittbild eines Audioschuhs 2 dargestellt. Der Audioschuh 2 ist nicht auf das Hörgerät 1 aufgesteckt.In FIG. 2 is a sectional view of a portion of a hearing aid 1 and a sectional view of an audio shoe 2 shown. The audio shoe 2 is not attached to the hearing aid 1.

Das Hörgerät weist eine um eine Schwenkachse 12 schwenkbare Batterielade 15 auf, die mittels eines Hebels 5 geöffnet und auch wieder geschlossen werden kann. In der Abbildung ist die Batterielade 15 vollständig in das Hörgeräte-Gehäuse eingeschwenkt. Auf der Außenseite der Batterielade 15 befindet sich eine Verriegelung in Form einer Einkerbung 13, die eine als Rastnase ausgeführte senkrechte Kante sowie eine weitere, abgeflachte Kante besitzt.The hearing device has a pivotable about a pivot axis 12 battery drawer 15 which can be opened by means of a lever 5 and also closed again. In the figure, the battery tray 15 is fully pivoted into the hearing aid housing. On the outside of the battery door 15 is a lock in the form of a notch 13, which has a designed as a latching nose vertical edge and another, flattened edge.

Das Hörgeräte-Gehäuse weist eine Öffnung 20 auf, die zu einer Vertiefung 24 innerhalb des Hörgeräte-Gehäuses führt. Die Vertiefung 24 weist eine bogenförmig konkav ausgestaltete Kontur auf. Sie führt zu einer Hinterschneidung 21 im Hörgeräte-Gehäuse, d.h. zu einem zwar von außerhalb des Gehäuses zugänglichen, aber von außen gesehen hinter der Gehäusewand angeordneten Raum innerhalb des Gehäuses. Der der Hinterschneidung 21 gegenüberliegende Bereich der Öffnung 20 ist als Widerlager 22 ausgeführt, welches eine geradlinige Schubbewegung in die Hinterschneidung 21 hinein bzw. eine geradlinige Zugbewegung aus der Hinterschneidung 21 heraus verhindert.The hearing aid housing has an opening 20, which leads to a recess 24 within the hearing aid housing. The recess 24 has an arcuate concave contour. It leads to an undercut 21 in the hearing aid housing, i. to a indeed accessible from outside the housing, but seen from the outside behind the housing wall space within the housing. The region of the opening 20 opposite the undercut 21 is embodied as an abutment 22, which prevents a straight-line pushing movement into the undercut 21 or a rectilinear pulling movement out of the undercut 21.

Im Hörgeräte-Gehäuse ist ein Schaltungsträger 16 angeordnet, der Leiterbahnen aufweist und mit Signalverarbeitungskomponenten und sonstigen elektronischen Komponenten des Hörgeräts 1 bestückt ist. Innerhalb der Hinterschneidung 21 sind elektrische Kontaktflächen 23 des Schaltungsträgers 16 angeordnet. Sie sind an der Innenseite des Hörgeräte-Gehäuses angeordnet. Dadurch sind sie wegen des Widerlagers 22 und wegen ihrer außenseitigen Anordnung in der Hinterschneidung 21 von außen nicht sichtbar und nicht durch eine lineare Bewegung direkt zugänglich. Insofern sind die Kontaktflächen 23 äußeren Einflüssen nicht direkt ausgesetzt.In the hearing aid housing, a circuit carrier 16 is arranged, which has conductor tracks and is equipped with signal processing components and other electronic components of the hearing aid 1. Within the undercut 21 electrical contact surfaces 23 of the circuit substrate 16 are arranged. They are arranged on the inside of the hearing aid housing. As a result, they are not visible from the outside because of the abutment 22 and because of their outside arrangement in the undercut 21 and not directly accessible by a linear movement. In this respect, the contact surfaces 23 are not directly exposed to external influences.

Der Audioschuh 2 weist eine Batterieladenaufnahme 11 auf, die als Hohlraum ausgebildet ist und die Batterielade 15 aufnehmen kann. Zudem ist eine Hebelaufnahme 10 vorgesehen, die den Hebel 5 der Batterielade in sich aufnehmen kann.The audio shoe 2 has a battery charging receptacle 11 which is formed as a cavity and can receive the battery charger 15. In addition, a lever holder 10 is provided which can accommodate the lever 5 of the battery charger in itself.

Eine Verriegelungskomponente des Audioschuhs 2 wird durch einen Riegel 4 gebildet. Der Riegel 4 ist auf einem Kipphebel angeordnet, der um eine Kippachse 6 gekippt werden kann und durch eine Feder 7 beaufschlagt wird. Durch die Feder wird der Kipphebel in die geschlossene, verriegelte Position gedrückt. Der Riegel 4 ist derart gestaltet, dass er in die Einkerbung 13 auf der Batterielade eingreifen kann. Er weist eine als senkrechte Kante ausgeführte Rastnase aus, die mit der Rastnase in der Einkerbung 13 zusammenwirkt. Sobald der Riegel 4 in die Einkerbung 13 eingreift verhindern die beiderseitigen Rastnasen eine Bewegung des Audioschuhs 2 vom Hörgerät 1 weg (in der Abbildung also nach unten).A locking component of the audio shoe 2 is formed by a latch 4. The bolt 4 is arranged on a rocker arm, which can be tilted about a tilting axis 6 and is acted upon by a spring 7. The spring pushes the rocker arm into the closed, locked position. The latch 4 is designed so that it can engage in the notch 13 on the battery charger. He has a designed as a vertical edge latch, which with the locking lug in the notch 13 cooperates. As soon as the latch 4 engages in the notch 13, the mutual latching lugs prevent a movement of the audio shoe 2 away from the hearing aid 1 (ie downwards in the illustration).

Der Audioschuh 2 weist eine Haltenase 8 auf. Die Haltenase 8 ist annährend kreisbogenförmig gestaltet und weist insbesondere eine kreisbogenförmige Oberfläche an einer Seite auf (in der Abbildung die dem Hörgerät 1 zugewandte Längsseite). In die Haltenase 8 münden elektrische Leitungen des Audioschuhs 2, die auf der Haltenase 8 in Kontaktflächen 9 enden bzw. mit diesen verbunden sind.The audio shoe 2 has a retaining lug 8. The retaining lug 8 is designed approximately circular arc-shaped and in particular has a circular arc-shaped surface on one side (in the figure, the long side facing the hearing aid 1). In the retaining lug 8 open electrical lines of the audio shoe 2, which ends on the retaining lug 8 in contact surfaces 9 and are connected thereto.

In Figur 3 ist ein Schnittbild des vorangehend beschriebenen Teils eines Hörgeräts 1 und eines Audioschuhs 2 in veränderter Position zueinander dargestellt, nämlich während des Aufsteckens des Audioschuhs 2 auf das Hörgerät 1. Im übrigen sind dieselben Komponenten wie in der vorangehenden Figurenbeschreibung unter Verwendung derselben Bezugszeichen verwendet, so dass für eine detaillierte Erläuterung auf die vorangehende Figurenbeschreibung verwiesen wird.In FIG. 3 FIG. 2 shows a sectional view of the above-described part of a hearing aid 1 and an audio shoe 2 in a different position relative to one another, namely during the attachment of the audio shoe 2 to the hearing aid 1. Otherwise, the same components as in the preceding description of the figures are used using the same reference symbols, so that for a detailed explanation, reference is made to the preceding description of the figures.

Der Audioschuh 2 ist beim Aufstecken auf das Hörgerät 1 dargestellt und mit diesem bereits leicht in Berührung, nämlich an der Haltenase 8 des Audioschuhs 2 und der Vertiefung 24 des Hörgeräts 1. Zum Aufstecken muss nämlich zunächst die Haltenase 8 in die Vertiefung 24 eingeführt werden. Da die zur Vertiefung 24 führende Öffnung 20 größer als die Spitze der Haltenase 8 ist, erfordert das Einführen keine hohe Genauigkeit in der Bewegung.The audio shoe 2 is shown when plugging on the hearing aid 1 and with this already slightly in contact, namely on the retaining lug 8 of the audio shoe 2 and the recess 24 of the hearing aid 1. For attaching namely the retaining lug 8 must first be inserted into the recess 24. Since the opening 20 leading to the recess 24 is larger than the tip of the retaining lug 8, the insertion does not require high accuracy in the movement.

Aus der Figur wird erkennbar, dass die Haltenase 8 zwar zunächst durch eine geradlinige Bewegung in die Vertiefung 24 wie dargestellt eingeführt werden kann. Ein weiteres Einführen ist jedoch wegen der im ganzen gebogenen Form der Haltenase 8 und der geometrischen Gestaltung der Öffnung 20, der Vertiefung 24 und teilweise auch des Widerlagers 22 nicht mehr durch eine geradlinige Bewegung möglich.From the figure it can be seen that the retaining lug 8, although initially by a rectilinear movement into the recess 24 as shown can be introduced. However, further insertion is no longer possible due to the generally curved shape of the retaining lug 8 and the geometric configuration of the opening 20, the recess 24 and partially also the abutment 22 by a rectilinear movement.

Vielmehr muss die Haltenase 8 für weiteres Einführen um die im Bereich der Hinterschneidung 21 liegende Seite der Öffnung 20 herum rotiert werden (in der Abbildung also im Uhrzeigersinn). Eine solche Rotationsbewegung wird durch die bogenförmige Gestaltung der Vertiefung 24 und der Haltenase 8 unterstützt und erleichtert. Denn die konkave Bogenform der Vertiefung 24 nimmt die konvexe Bogenform der der Vertiefung 24 zugewandten Seite der Haltenase 8 ersichtlich auf.Rather, the retaining lug 8 must be rotated for further insertion around the lying in the region of the undercut 21 side of the opening 20 around (in the figure so in a clockwise direction). Such a rotational movement is supported and facilitated by the arcuate configuration of the recess 24 and the retaining lug 8. Because the concave arc shape of the recess 24 takes the convex arc shape of the recess 24 facing side of the retaining lug 8 on.

In Figur 4 ist ein Schnittbild des vorangehend beschriebenen Teils eines Hörgeräts 1 mit aufgestecktem vorangehend beschriebenen Audioschuh 2 unter Verwendung derselben Bezugszeichen dargestellt, so dass für eine detaillierte Erläuterung auf die vorangehenden Figurenbeschreibungen verwiesen wird.In FIG. 4 1 is a sectional view of the above-described part of a hearing aid 1 with the above-described audio shoe 2 attached using the same reference symbols, so that reference is made to the preceding description of the figures for a detailed explanation.

Der Audioschuh 2 ist durch die vorangehend erläuterte Rotationsbewegung um die im Bereich der Hinterschneidung 21 liegende Seite der Öffnung 20 herum (im Uhrzeigersinn) vollständig auf das Hörgerät 1 aufgesteckt. Die Haltenase 8 ist damit durch die Öffnung 20 und Vertiefung 24 hindurch in die Hinterschneidung 21 eingeführt.The audio shoe 2 is completely attached to the hearing aid 1 by the above-explained rotational movement about the side of the opening 20 located in the region of the undercut 21 (clockwise). The retaining lug 8 is thus inserted through the opening 20 and recess 24 into the undercut 21.

Gleichzeitig ist auf der gegenüberliegenden Gehäuse-Seite der Riegel 4 des Audioschuhs 2 in die Einkerbung 13 auf der Batterielade 15 eingerastet. Das Einrasten erfolgte durch die Kraft der Feder 7, die denn Kipphebel in entsprechender Richtung um die Kippachse 6 gekippt hat. Die Beauschlagung mit der Kraft der Feder 7 bewirkt auch, dass der Riegel 4 in der Einkerbung 13 verbleibt und damit im geschlossenen, verriegelten Zustand. Die Haltenasen des Riegels 4 und der Einkerbung 13 bewirken, dass der Audioschuh 2 bei geschlossener Verriegelung nicht vom Hörgerät 1 weg abgezogen bzw. nicht um die im Bereich der Hinterschneidung 21 liegende Seite der Öffnung 20 herausrotiert werden kann (also im Gegenuhrzeigersinn abgenommen).At the same time, the latch 4 of the audio shoe 2 is latched into the notch 13 on the battery door 15 on the opposite side of the housing. The engagement was made by the force of the spring 7, which has tilted the rocker arm in the corresponding direction about the tilting axis 6. The Beauschlagung with the force of the spring 7 also causes the latch 4 remains in the notch 13 and thus in the closed, locked state. The retaining lugs of the bolt 4 and the notch 13 cause the audio shoe 2 is not withdrawn from the hearing aid 1 when the lock is closed or can not be rotated around the side of the opening 20 located in the region of the undercut 21 (ie taken counterclockwise).

Auf der Seite der Öffnung 20 und Haltenase 8 wiederum verhindert das Widerlager 22, dass der Audioschuh 2 vom Hörgerät 1 weg abgezogen werden kann. Denn die Haltenase 8 wird an einer solchen geradlinigen Bewegung vom Widerlager 22 gehindert, an dem die konvex bogenförmige Seite der Haltenase 8 ansteht. Das Widerlager 22 ist dazu vorgesehen, ein solches geradliniges Abziehen des Audioschuhs 2 zu verhindern. Daraus wird klar, dass es durch einen der Hinterschneidung 21 gegenüberliegenden Teil der Öffnung 20 und/oder Vertiefung 24 gebildet wird.On the side of the opening 20 and retaining lug 8 in turn prevents the abutment 22 that the audio shoe 2 can be removed from the hearing aid 1 away. For the retaining lug 8 is prevented from such rectilinear movement by the abutment 22, to which the convex arcuate side of the retaining lug 8 is present. The abutment 22 is intended to prevent such rectilinear removal of the audio shoe 2. From this it is clear that it is formed by an undercut 21 opposite part of the opening 20 and / or recess 24.

Somit verhindern auf der einen Seite Haltenase 8 und Widerlager 22 und auf der anderen Seite Riegel 4 und Einkerbung 13, dass der Audioschuh 2 vom Hörgerät 1 abgezogen werden kann. Er kann nur durch Lösen des Riegels 4, als durch Betätigen des Riegel-Kipphebels, abgezogen werden, weil nur dadurch die Rotationsbewegung aus der Hinterschneidung 21 heraus und am Widerlager 22 vorbei ermöglicht wird.Thus prevent on the one hand retaining lug 8 and abutment 22 and on the other side latch 4 and notch 13 that the audio shoe 2 can be deducted from the hearing aid 1. It can be deducted only by loosening the bolt 4, as by pressing the latch rocker arm, because only thereby the rotational movement of the undercut 21 out and the abutment 22 is made possible over.

In Figur 5 ist der Audioschuh 2 perspektivisch dargestellt. die Draufsicht zeigt die dem Hörgerät 1 zugewandte Seite des Audioschuhs 2 mit einer als Batterieladenaufnahme 11 ausgebildeten Öffnung. Auf einer Seite der Öffnung befindet sich der Riegel 4 und auf der gegenüberliegenden Seite die Haltenase 8. Auf der Haltenase 8 sind die elektrischen Kontaktflächen 9 angeordnet.In FIG. 5 the audio shoe 2 is shown in perspective. The top view shows the hearing device 1 facing side of the audio shoe 2 with a trained as a battery charging receptacle 11 opening. On one side of the opening is the latch 4 and on the opposite side the retaining lug 8. On the retaining lug 8, the electrical contact surfaces 9 are arranged.

In Figur 6 ist jeweils ein Teil des Hörgeräts 1 und des Audioschuhs 2 während des Aufsteckens des Audioschuhs 2 perspektivisch dargestellt. Die Haltenase 8 ist durch die Öffnung 20 hindurch und am Widerlager 22 entlang teilweise in die Vertiefung 24 eingeführt. Auf der Haltenase 8 sind die elektrischen Kontaktflächen 9 erkennbar.In FIG. 6 In each case a part of the hearing aid 1 and the audio shoe 2 during the Aufsteckens the audio shoe 2 is shown in perspective. The retaining lug 8 is inserted through the opening 20 and partially inserted into the recess 24 along the abutment 22. On the retaining lug 8, the electrical contact surfaces 9 can be seen.

Auf Seite des Hörgeräts 1 ist der Schaltungsträger 16 mit seinen elektrischen Kontaktflächen 23 dargestellt. Diese Darstellung zeigt Teile aus dem Inneren des Hörgeräte-Gehäuses, die normalerweise durch das Hörgeräte-Gehäuse hindurch nicht zu sehen wären; insofern ist in der Darstellung das Gehäuse teilweise weggelassen. Die Kontaktflächen 23 sind in der Hinterschneidung 21 angeordnet.On the side of the hearing aid 1, the circuit carrier 16 is shown with its electrical contact surfaces 23. This illustration shows parts of the interior of the hearing aid housing that are not normally through the hearing aid housing to be seen; insofar as the housing is partially omitted in the illustration. The contact surfaces 23 are arranged in the undercut 21.

In Figur 7 ist wiederum jeweils ein Teil des Hörgeräts 1 und des Audioschuhs 2 perspektivisch dargestellt, diesmal jedoch bereits zusammengesteckt. Es sind dieselben Bezugszeichen wie in den vorangehenden Figuren verwendet, so dass für eine detaillierte Erläuterung auf die vorangehenden Figurenbeschreibungen verwiesen wird. Es ist erkennbar, dass die Haltenase 8 in die Hinterschneidung 21 eingeführt ist. Die Kontaktflächen 9 der Haltenase 8 sind mit den Kontaktflächen 23 des Schaltungsträgers 16 in Verbindung. Damit ist der Audioschuh 2 sowohl mechanisch als auch elektrisch mit dem Hörgerät 1 verbunden.In FIG. 7 In turn, each part of the hearing aid 1 and the audio shoe 2 is shown in perspective, this time, however, already put together. The same reference numbers are used as in the preceding figures, so that for a detailed explanation reference is made to the preceding figure descriptions. It can be seen that the retaining lug 8 is inserted into the undercut 21. The contact surfaces 9 of the retaining lug 8 are connected to the contact surfaces 23 of the circuit substrate 16 in connection. Thus, the audio shoe 2 is both mechanically and electrically connected to the hearing aid 1.

Ein Grundgedanke der Erfindung lässt sich wie folgt zusammenfassen: Die Erfindung betrifft ein Hörgerät mit Audioschuh-Schnittstelle, einen zugehörigen Audioschuh, sowie ein Hörgerätesystem umfassend ein Hörgerät und einen Audioschuh. Ein Grundgedanke der Erfindung besteht in einem Hörgerät 1 mit einem Gehäuse, in dem eine Hinterschneidung 21 und ein Widerlager 22 vorgesehen sind. Das Widerlager 22 ist der Hinterschneidung 21 gegenüber liegend angeordnet. Hinterschneidung 21 und Widerlager 22 sind derart ausgeführt, dass eine Haltenase 8 eines Audioschuhs 2 mit einer Rotationsbewegung in die Hinterschneidung 21 einführbar ist. Das Widerlager 22 ist derart ausgeführt, dass eine in die Hinterschneidung 21 eingeführte Haltenase 8 nur durch eine gegenläufige Rotationsbewegung wieder aus der Hinterschneidung 21 ausführbar ist. Weiter ist eine Verriegelung vorgesehen, durch die ein die gegenläufige Rotationsbewegung eines aufgesteckten Audioschuhs 2 verhindert wird. Die Hinterschneidung im Gehäuse gewährleistet eine hohe Stabilität der mechanischen Verbindung. Sie ermöglicht den Verzicht auf aus dem Gehäuse herausstehende Komponenten und ist daher optisch und in der Handhabung gefällig. Es werden keine zusätzlichen separaten Bauteile wie Achsen, Achsaufnahmen, o.ä. für die mechanische Verbindung benötigt, so dass sie in der Fertigung hinsichtlich der Fertigungsschritte und Bauteile-Logistik günstig ist. Sind zudem die elektrischen Kontakte zwischen Audioschuh 2 und Hörgerät 1 in der Hinterschneidung 21 angeordnet, so sind auch diese optisch verborgen und gegen äußere Einflüsse gut geschützt.A basic idea of the invention can be summarized as follows: The invention relates to a hearing aid with audio shoe interface, an associated audio shoe, and a hearing aid system comprising a hearing aid and an audio shoe. A basic idea of the invention consists in a hearing aid 1 with a housing in which an undercut 21 and an abutment 22 are provided. The abutment 22 is disposed opposite the undercut 21. Undercut 21 and abutment 22 are designed such that a retaining lug 8 of an audio shoe 2 with a rotational movement in the undercut 21 is insertable. The abutment 22 is designed such that an inserted into the undercut 21 retaining lug 8 is executable only by an opposite rotational movement back from the undercut 21. Next, a lock is provided by which the opposite rotational movement of a plugged audio shoe 2 is prevented. The undercut in the housing ensures high stability of the mechanical connection. It eliminates the need for protruding from the housing components and is therefore pleasing visually and in handling. There are no additional separate components such as axles, axle mounts, or similar. for the mechanical connection needed so that it is favorable in terms of manufacturing steps and component logistics in manufacturing. If, in addition, the electrical contacts between the audio shoe 2 and the hearing device 1 are arranged in the undercut 21, these are also optically hidden and well protected against external influences.
